PROBLEM TO BE SOLVED: To provide a booster having a means that returns a pressurized medium from a pressurizing point to the booster side, in order to reduce the pressure of the pressurizing point or keep it a constant pressure.
SOLUTION: This booster 1 is a double-acting type equipped with a double- action cylinder, that can continuously pressurize the pressurized medium and can boost a low-pressure medium. Furthermore, the booster 1 has the means that returns the pressurized medium from the pressurizing point to the booster side. The means forms to set each on-off valve 6 to 9 into each channel 2 to 5, that is connected to each port of the booster 1 individually. Accordingly, by securing channels for reducing the pressure by the switching operations of the on-off valves 6 to 9, the means can reduce the pressure of the pressurizing point or keep it prescribed pressure.
